Container-native load balancing removes the node hop

GKE-managed Layer 7 load balancers use GCE_VM_IP_PORT Network Endpoint Groups (NEGs) so health checks and requests target Pod IP and port directly.

1ClientConnects to an external or internal Application Load Balancer.

2FrontendTerminates the connection and evaluates routing policy.

3Backend serviceSelects a healthy zonal NEG.

4NEG endpointMaps directly to the Pod alias IP and target port.

5Ready PodReceives traffic without a NodePort and kube-proxy hop.

A readiness gate can keep a Pod out of service until the load balancer sees it as healthy.

Container-native load balancing removes the node hop

Container-native load balancing is easiest to understand by separating the Kubernetes contract from the Google Cloud implementation. A NEG is a group of endpoints. For GKE Layer 7 products, those endpoints are Pod IP and port pairs, enabling direct health checks and traffic delivery. The Kubernetes objects stay familiar, but GKE supplies controllers, infrastructure and safe defaults around them. This is why a team can move from an on-premises cluster without rewriting every workload, while still needing to redesign networking, identity and operational ownership for the cloud environment.

A useful inspection step is `kubectl get svc shopwave-web -o yaml`. Read the output as evidence, not as a ritual: first confirm the desired object exists, then look at status conditions, events and the Google Cloud resource it represents. In production, capture the expected result in a runbook or automated check so an operator can distinguish slow reconciliation from a configuration error.

Production gotcha: Kubernetes readiness and load-balancer health are related but distinct; inspect readiness gates and backend health during slow rollouts. The safe habit is to verify quotas, regional availability and feature support against current Google Cloud documentation before rollout. The last networking slide chooses internal or external exposure.
